Which probably means he doesn't know jack about most of the other sciences out there, like for example Geology, Archeology, Biology or more specific Evolutionary Biology. :P

When it comes to logic and our current knowledge, there's simply no denying the whole religious answer for most related topics doesn't make much sense.

In fact, said person as a mathematician probably will know chance is something illogical when it comes to real life events. Illogical as in something might happen 8 out of 10 times and therefore have an 80% chance of happening, this doesn't mean said event must happen 8 times or even just one time.

I'm thinking whatever the reason why he's quite open minded on the issue probably has little to do with his intelligence. Even brilliant people can have a huge lack of understanding because of a lack of knowledge (or lack of curiosity for a certain topic).
